If you’re going to buy a relatively bulky power supply, why not go for one with a capacity so huge it could charge your iPhone 7 over 61 times? That’s exactly what the River Mobile Power station is capable of, thanks to its massive 116,000 mAh capacity. Not only does it have a huge capacity, it can also output up to 500W from a array of ports, allowing you to power up to 11 devices simultaneously. What ports does it carry?

The thing can power a refrigerator for 10+ hours, for crying out loud. It’s also waterproof and weather proof, withstanding temperatures of -4° to 140° F, making it an ideal camping companion. Also, the battery management system is brilliant:

It’s a “smart” system, that allows RIVER to 1) automatically adjust the power output to the Wattage your device needs, 2) regulate temperature so devices don’t shut down by starting a fan if too hot, and informing you if it’s too cold, and 3) connect individually to each of the 11 output ports so if one were to short circuit or max-out the other 10 would continue charging.

Weighing in at a hefty 11lbs (5kg), it’s definitely not light weight but still isn’t so heavy as to not be portable.

Prices start with a $459 Early Bird pledge and are expected to go up to $699 retail. Shipping starts in June 2017.

The ZeroLemon SolarJuice 10000mAh Battery is one of our bestsellers, and for good reason. You’re looking at a 10,000mAh battery pack that can be charged with the power of the sun, and also happens to be waterproof. And it’s $30!

Power up your gadgets in the most unexpected places with the extremely compact SolarJuice battery pack. SolarJuice charges up at home like your average battery pack, but also lets you add extra juice on-the-go using its built-in solar panel—so you’ll never be left unplugged from the digital world.

There are portable power packs, and then there’s Anker’s PowerHouse. It’s about the size (7.9 x 6.5 x 5.7 inches) and weight (9.3 lbs) of a concrete construction brick, so might weigh things down a bit should you decide to toss it in a backpack. That being said, what you’re trading for that all that heft is a massive charging capacity. At 120,000 mAh, the 434Wh behemoth is able to fully recharge a laptop 15 times over. For reference, an iPhone 6 Plus has a 2,950 mAh battery. It outputs all that electricity through a 12V socket, an AC socket, or 4 USB-ports. It’s meant to take with you when you’re off grid and power your electronics for long periods. The PowerHouse is able to feed most things, like stereos, TVs, and lamps, but it might choke on higher-voltage appliances like toasters or hair-dryers. Still, no one is expecting you to try to blow-dry your hair while your husbands sets up the tent, so the point is moot.

Look, 50,000 mAh is a lot of capacity. For reference, an iPhone 6 Plus is rated at 2,915 mAh. So that means that with the Go Green 50,000mAh Solar Power Bank, you could charge that device 17 times over before the power bank itself need to be topped off! The best part about it, is that it can itself be recharged with the power of the sun.

Eliminate your chances of a dead phone for good with this handy solar power bank. Just power it up anywhere under the sun (literally), and plug your phone or other USB device into it for a quick recharge. And with a whopping 50,000mAh in charge capacity, you’ll never find yourself waiting on extra juice again.

Did you buy an Apple Watch? Aw, we’re sorry to hear that. Now you’re stuck with a marginally useful smart watch with a battery that barely lasts through the day. Not all hope is lost though, since watch band makers are getting increasingly ingenious and designing products that go beyond aesthetics. The Prime Strap is a rather chunky band that houses two 150mAh swappable batteries, which can externally charge your watch through its 6-pin port. You can carry extra batteries with you in a slick case, and simply switch them out once you’re running low on power. The case, incidentally, also charges the batteries in 2.5 hours, so you can redo the cycle once they run out.

Granted, you’ll have to have thicker wrists for the ensemble not to look weird on you, but if you’re really concerned about getting the most out of your questionable purchase, you’ll likely want to pony up the $199 pledge.

The ZeroLemon SolarJuice 10000mAh Battery is a best-seller in the OhGizmo store. And it’s easy to understand why: 10,000mAh in a device that can be charged by the sun. Two USB ports. Waterproof. And more, for $30? It’s a ridiculously good deal.

Power up your gadgets in the most unexpected places with the extremely compact SolarJuice battery pack. SolarJuice charges up at home like your average battery pack, but also lets you add extra juice on-the-go using its built-in solar panel—so you’ll never be left unplugged from the digital world.

Batteries: we all hate them. But like it or not, we have to live with them for now, so why not make our lives a little easier and go the way of rechargeables? The SunLabz Rechargeable AA Battery Bundle gives you eight 2,800mAh rechargeable batteries, along with a charger, for $30!

Rather than purchase pack after pack of AA batteries, switch to rechargeable. Not only will you be saving money on single-use battery purchases, but you’ll be throwing one less toxic battery into a landfill every time you run out of juice.

– Make an environmental difference by reusing your batteries
– Get 2 or 3 times the capacity of an equivalent NiCD cell
– Enjoy high-performance functionality
– Save money spent on single-use batteries
– Recharge 1000+ times
– Recycle the batteries once they finally tap out

Of course these batteries wouldn’t be very useful without a charger, so here’s the lowdown on that.

Rechargeable batteries mean nothing without a manner of recharging them. Choose the best option available—this charger is efficient, fast, and even boasts a convenient LCD screen to keep tabs on your charging status.

If you’re a foreman, or project manager, part of your job just got a little easier. DeWalt will be releasing “a new line of Bluetooth rechargeable batteries that can be connected to a smartphone app for checking their charge status—or remotely disabling them.” They come in 2.0Amp and 4.0Amp versions, and all pair with an iOS or Android device for easy management. Managers can keep track of specific inventory at a job site, charge levels on each battery, and can disable individual ones or all of them in one go. You can set things so that you receive a notification if a battery is taken out of range, and it can also be auto-disabled if that happens. It’s even possible to lend tools for a specified amount of time, after which the battery will be disabled to force the tool’s return.

When you’re on a job site, you have tons of things to take care of and keep track. Every little bit helps, and these batteries from Dewalt should be well received. It’s $99 and $139 for each, which seems like a lot until you end up preventing a theft or two, then they pay for themselves.
